Question

Match List I with List II:

List I		List II
A	Citric acid cycle	I	Cytoplasm
B	Glycolysis	II	Mitochondrial matrix
C	Electron transport System	III	Intermembrane space of mitochondria
D	Proton gradient	IV	Inner mitochondrial membrane

Choose the correct answer from the options given below:

• A. A-I, B-II, C-III, D-IV
• B. A-II, B-I, C-IV, D-III
• C. A-III, B-IV, C-I, D-II
• D. A-IV, B-III, C-II, D-I

Answer 1

The Correct Option is B

To correctly answer this matching question, identify the cellular location of each biological process. The associations are as follows:

1. Citric acid cycle (Krebs cycle): Occurs within the mitochondrial matrix. Correspondingly, A aligns with II.
2. Glycolysis: Takes place in the cytoplasm of the cell. Therefore, B corresponds to I.
3. Electron transport System: Located in the inner mitochondrial membrane. Consequently, C matches with IV.
4. Proton gradient: Established across the intermembrane space of mitochondria. Thus, D is paired with III.

The correct answer, derived from these pairings, is: A-II, B-I, C-IV, D-III
